Sam and Dean thought their life was a living hell. But when they find a young girl who shares their name and family business, neither of them can help but be curious about who this girl really is and what she can do for them.

What if Cassie wasn't Dean's only "old friend"? Enter Alexandria: she's kicking supernatural butt and taking demonic names. She knew the Winchesters, once, but they left - and that was that. Or so she thought. But then a certain hunter waltzes into a bar, ten years later, asking for her help in finding his father. Can she dive back in? Does she even have a choice in the matter?
